Material and Craftsmanship: High-strength alloy steel is preferred. Check for even and secure welds, and a good surface anti-rust treatment (such as electroplating or plastic spraying).
Design Details: Check for a wide and stable base, thick, non-slip rubber pads on the support head, and anti-drop features on the safety latch.
Certification Standards: Check for relevant quality and safety certifications (such as CE, GS, etc.).
Brand and Reputation: Choose a well-known brand with positive user reviews for greater quality assurance.
